How do I get correct substring using Regex

Question

How I can get fr and en from ["fr", "en"] using regex? I have tried to use split("[\\W]+") but it gives me 3 items ("", "fr" and "en").

How can I do this without getting that first empty string, and just get fr and en?

(?<=")[^",]+(?=")

Simply do a match instead of split.See demo.

Instead of split you should use this regex to match the desired parts:

(?<=")\w+(?=")

RegEx Demo

In Java:

String str = "[\"fr\", \"en\"]";
Pattern p = Pattern.compile("(?<=\")\\w+(?=\")");
Matcher = p.matcher(str);
while (m.find())
    System.out.println(m.group());

Output:

fr
en
